Actually, I just thought of one.
Let's say mod.py looks like this:
How do we get the code for the g function?
With an AST, it's obvious—you may not get sufficient/correct context, but at least you can get to it.
With a compiled module, whether we explicitly compile mod.py or import it or whatever… well, there's a code object for g compiled in there, and it even knows that it's part of module fc, and from line 1 of fc.py, and so on… but you can't access it as fc.g, or anything else obvious, without picking through the compiled code format.
